Abstract

L'invention concerne des dispositifs de marqueur électromagnétique permettant de localiser des objets cachés ou enfouis. Un mode de réalisation comprend : une antenne ayant une pluralité d'enroulements conducteurs enfermés dans un boîtier constitué d'un matériau à faible constante diélectrique ; et un circuit électronique comprenant une carte de circuit imprimé sur laquelle sont disposés des éléments de circuit et qui est électriquement couplée aux enroulements conducteurs par le biais d'un connecteur. Les éléments de circuit reçoivent un signal d'entrée ayant une première fréquence en provenance d'un émetteur au-dessus du sol, convertissent le signal d'entrée en alimentation électrique pour alimenter le circuit électronique, génèrent, en réponse au signal d'entrée, un signal de sortie ayant une seconde fréquence différente de la première fréquence, puis fournissent le signal de sortie, au moyen de l'élément d'antenne, à un récepteur au-dessus du sol.
